If 20 g KCL is dissolved in 100g of water at 20 degrees C, is the solution unsaturated, saturated, or supersaturated?

Is it above the KCl line, on it, or below it?
it looks like it is above
is it saturated
The 20 point is BELOW the line. that means unsaturated.
To determine whether the solution is unsaturated, saturated, or supersaturated, we need to compare the amount of solute (KCl) present in the solution with its maximum solubility at the given temperature (20 degrees C).
First, let's find out the maximum solubility of KCl in water at 20 degrees C. This information can be obtained from a solubility table or experimentally determined data. According to the solubility table, the maximum solubility of KCl in water at 20 degrees C is approximately 34 grams per 100 grams of water.
Now, let's compare this value with the amount of KCl dissolved in the solution. It is given that 20 grams of KCl is dissolved in 100 grams of water.
Since the amount of KCl in the solution (20 grams) is less than the maximum solubility (34 grams) at 20 degrees C, the solution is considered unsaturated.
